Sputters and dies. Not a problem when cold but is almost undriveable when warm. Poor gas mileage and popping under deceleration. List of things replaced:

-o2 sensor
-thermostat
-maf
-tps
-Fuel Filter
-Spark Plugs
-cap and rotor

Next logical step is fuel pump. ECU isn't throwing any codes. Anyone have any other ideas?

yup gotta be fuel or air leaks?

KiLLeR2001 · 01-24-2013, 12:40 AM

Gas tank venting properly? Gas cap good? Fuel check valve working?

Anyone else with any ideas? I'm going to check for vacuum leaks tonight.

Sounds like the fuel pump is going out

sounds like its temperature related issue. try a new coolant temp sensor.

Good call. I'll get that tomorrow.
